ls1 to a 383
How would I go about turning my ls1 into a 383 stroker? Can I use the same block, and if so, what do I need to do to it? I want it bulletproof, no shortcuts.

yeah just check out the sponsors on the right... scoggin dickey has some great things at low prices. i would also take a look at tsp.
you would need to look at a rotating assembly, clean up your block, and then might as well do a h/c set up b/c it wont be anyhting to special with stock parts on a 383 imo

I am in the process of doing this right now, My block is fine I am getting all the parts together, You can look for used parts on this site or ebay but be informed they will need to be checked out, possibly machined, I scored a set of Lunati probillet forged I beams off ebay (1300 dollars new) for 400 dollars, took them to the machine shop they were perfect, Good deal. I bought a callies racemaster stroker crank off ebay (over 1500 dollars new) I paid 500 checked out perfect, I will go with brand new pistons but All the parts have to be balanced. If you want to go with new matched kit I would say Right now that Texas Speed has the best deals I have seen, complete rotating kits, with all kinds of options, Eagle parts will probably be the most budget friendly parts, callies are better, You can get a complete lunati kit but its about twice what any other kit costs. Texas speed also sells complete shortblocks. If you do it yourself with a rotating kit You will get to reuse your stock block, will have to have it cleaned and honed, new cam bearings, You will also probably have to clearance the bottom of the cylinder walls a little bit, due to the increased stroke, you may have a rod bolt come into contact.
Here is a good read that will give you a great deal of knowledge of what is involved. Hope this helps you some

I just fired my 383 build up for the first time last month. I got used lunati pistons and eagle h rods for 500 used, and the eagle stroker crank for 800 new. New main seals, rings, balence, and labor 1300. All together 2600 dollar shortblock. It might be just as affordable to buy a new shortblock 383.

There's a shop that does really good work. I knew I'd have to get the whole bottom end forged, and I've heard that hbeam rods were the way to go, I just didn't know how to prep the block for it. Custom top end is coming from Cali, I have a conference with the guy wednesday. I don't know the finals yet, but I think i'm getting a magnacharger to top it all off. I told them I wanted to dyno 600hp.

Well your looking at a 383 or 347. The 347 will be less by the cost of the crank plus the cost to magnaflux and polish your crank (150-250 in the states).
We can build it for you if your not comfortable with anyone up there, we've got a nice 427 long block going to Saskatchewan shortly and believe it or not shipping to him is only $300, cost me more to ship to Oregon
You want to do it right though, the s/c will want a solid base to boost.

Secondly, before honing the cylinders and setting the rings, it's a good idea to know for sure if you plan to supercharge or add nitrous. The additional heat generated from either application will cause the pistons/rings to expand more than they would in a naturally aspirated engine. Therefore, piston and ring clearance is critical if you are supercharging or using nitrous. Also, you mentioned using a magnacharger. What is the vehicle and model year are you putting this into? A magnacharger will be difficult to fit in a 4th Gen Camaro/Firebird. Just make sure it all fits before you buy.
Lastly, a search will answer most of your questions. Try it out!
